Our SiC-Graphite Crucible represents the pinnacle of crucible technology for silver melting applications. Utilizing advanced isostatic pressing , this crucible fuses high-purity silicon carbide (SiC) and synthetic graphite into a seamless, isotropic composite. The result is an ultra-dense, non-porous structure engineered to withstand extreme thermal, chemical, and mechanical stresses in silver melting furnaces (induction, resistance, or gas-fired). Designed specifically for high-value silver processing, it ensures minimal contamination, extended service life, and operational reliability.

• Material: Advanced composite of Silicon Carbide (SiC) and Graphite.

• Manufacturing Process: Hot Isostatic Pressing (HIP) - Ensures maximum density, uniformity, and strength.

• Structure: Isotropic, ultra-dense, pore-free microstructure.

• Surface: Hard, glassy, oxidation-resistant SiC-rich layer.

• Primary Application: Optimized for melting and holding pure Silver (Ag) and Silver alloys.

• Performance: Superior resistance to thermal shock, oxidation, erosion, and chemical attack by molten silver/fluxes.

• Durability: Significantly longer lifespan than standard graphite or clay-graphite crucibles.

• Thermal Properties: High thermal conductivity, excellent high-temperature strength, and dimensional stability.

• Purity: Minimizes contamination of molten silver.

• Availability: Customizable sizes and shapes to fit various furnace types (induction, resistance, gas).

They can be used for resistance furnace, induction furnace, biological particles furnace, gas furnace, coke oven, furnace oil, and gas furnace to melt gold, silver, copper, aluminum, tin, lead, zinc and other nonferrous metals, and various non-ferrous alloys.

• Bullion Production: High-yield melting of 1-100kg silver bars.

• Jewelry Casting: Contamination-free melting for investment casting.

• Silver Recycling: Corrosion resistance against metallic impurities (Cu, Zn, Pb).

• Continuous Operations: 24/7 furnace compatibility with minimal degradation.
